Problems solved by technology
[0002] Originally, the transportation of light bulb products was mainly carried out in full box packaging. With the continuous popularization of online sales, the actual sales process of light bulb products is basically based on individual transportation. Since the material of the light bulb itself is mainly glass material, in the During transportation, due to factors such as human handling, packaging, and careless handling by the user, the lamp is dropped, frequently causing the ceramic metal halide arc tube in the lamp to hit the glass, causing the outer bulb to break and the bulb to be unusable
[0003] At present, in order to solve the above problems, various manufacturers use metal sheets to wrap the arc tube on the main bracket in the lamp to prevent the arc tube from breaking the bulb when it is hit. The specific operation is to weld a metal sheet on the cathode bracket to wrap the anode. The tail of the porcelain tube, and because the arc tube has two poles (cathode and anode), this method will cause the ionization effect in the lamp to be generated quickly, which will greatly reduce the service life of the bulb

Embodiment Construction
[0022] In order to make the technical means of the present invention and the technical effects that can be achieved more clearly and more perfectly disclosed, an embodiment is provided hereby, and the following detailed description is given in conjunction with the accompanying drawings:
[0023] A ceramic metal halide lamp in this embodiment uses nickel, tungsten, molybdenum and other materials with good high temperature resistance and chemical stability, and sets a fixed frame made of pure nickel or stainless steel on the upper end of the arc tube to fix the arc tube. The upper end of the arc tube (the end away from the lamp cap) keeps the arc tube in the center without shaking; the first bracket adopts molybdenum wire or tungsten wire, and one or more wires are continuously bent at one end of the molybdenum wire or tungsten wire (the bend in this embodiment Around 3) annular rings (fixing rings) cover the lower end of the arc tube (the end near the lamp head), and the ring is...

The invention provides a ceramic metal halide lamp and relates to the technical field of bulbs. The ceramic metal halide lamp comprises a lamp holder, a glass outer cover, an inner tube and a ceramicmetal halide arc tube, wherein the inner tube is internally and fixedly provided with a first support. The ceramic metal halide lamp is characterized in that one end of the ceramic metal halide arc tube is fixed in the inner tube through the first support; one end of the ceramic metal halide arc tube is sleeved by a fixing ring formed by one or more continuous bends, and the fixing ring is fixedlyconnected with the first support; the first support is communicated with the lamp holder; and the first support and the fixing ring are made of the same material. By means of the fixing ring, an ionization effect can be avoided, and the ignition voltage output by a ballast can generate induction voltage on the fixing ring when the lamp is started, so that the lamp is easier to start, and the starting voltage of the lamp is greatly reduced.
Description
technical field [0001] The invention relates to a light bulb, in particular to a ceramic metal halide lamp. Background technique [0002] Originally, the transportation of light bulb products was mainly carried out in full box packaging. With the continuous popularization of online sales, the actual sales process of light bulb products is basically based on individual transportation. Since the material of the light bulb itself is mainly glass material, in the During transportation, due to human handling factors, packaging factors, and the user’s careless handling of the lamp, the lamp is dropped. Frequently, the ceramic metal halide arc tube in the lamp hits the glass and the outer bulb is broken, making the bulb unusable. [0003] At present, in order to solve the above problems, various manufacturers use metal sheets to wrap the arc tube on the main bracket in the lamp to prevent the arc tube from breaking the bulb when it is hit.
